EnzymeFlow: Generating Reaction-specific Enzyme Catalytic Pockets through Flow Matching and Co-Evolutionary Dynamics

  • 基于流匹配与分层预训练生成催化口袋。
  • 在32.8万对酶-反应数据上验证,生成口袋功能性强。
  • 适合酶工程与合成生物学研究者使用。

酶设计是生物技术关键领域,应用于药物开发到合成生物学。传统方法难以捕捉酶-底物相互作用的动态复杂性,尤其在催化过程中。为此,我们提出EnzymeFlow,一种结合流匹配、分层预训练及酶-反应共进化动态的生成模型,用于为特定底物和催化反应生成催化口袋。同时构建了一个大规模、精心筛选并验证的酶-反应对数据集,共包含328,192对,专为催化口袋生成任务设计。通过引入进化动态与反应特异性适应,EnzymeFlow能有效设计出高质量、功能性酶催化口袋。在新数据集上的实验表明其在生成可功能化口袋方面具有显著效果,为酶工程与合成生物学发展铺平道路。代码与演示笔记见https://github.com/WillHua127/EnzymeFlow。

原文摘要 · Abstract (English)

Enzyme design is a critical area in biotechnology, with applications ranging from drug development to synthetic biology. Traditional methods for enzyme function prediction or protein binding pocket design often fall short in capturing the dynamic and complex nature of enzyme-substrate interactions, particularly in catalytic processes. To address the challenges, we introduce EnzymeFlow, a generative model that employs flow matching with hierarchical pre-training and enzyme-reaction co-evolution to generate catalytic pockets for specific substrates and catalytic reactions. Additionally, we introduce a large-scale, curated, and validated dataset of enzyme-reaction pairs, specifically designed for the catalytic pocket generation task, comprising a total of $328,192$ pairs. By incorporating evolutionary dynamics and reaction-specific adaptations, EnzymeFlow becomes a powerful model for designing enzyme pockets, which is capable of catalyzing a wide range of biochemical reactions. Experiments on the new dataset demonstrate the model's effectiveness in designing high-quality, functional enzyme catalytic pockets, paving the way for advancements in enzyme engineering and synthetic biology. We provide EnzymeFlow code at https://github.com/WillHua127/EnzymeFlow with notebook demonstration at https://github.com/WillHua127/EnzymeFlow/blob/main/enzymeflow_demo.ipynb.
